There is no statisticlly significant affect of time on particle number. If I take all of the time variables out and just compare to depth, there is a relationship to depth p = 0.02. But the R^2 is only 6.5%. Pretty weak

PSD varies with depth, but doesn’t statistically relate to hor orday. Comparing the R2 values from models tells us that you explain 69% of varience with depth.

Flux small and flux tot track so closely because particle fractal dimension alpha, plus flux fractal dimension, gamma > |psd|. since the size distribution of the flux sould be PSD + ag (psd is negative in this case). Yo ucan see the variance at the one depth where psd is flatest at the very top.

Just station 043

We are smoothing the station 043 data, with respect to depth and time. We are using this station because it is the only one to extend past 2000m. We find that the other profiles seem to give strange values near the ends of the ranges of the gams.
